Description
Technical field
The utility model relates to mechanical fixture technology field, particularly relates to liftable pin roll end face groove milling stationary fixture.
Background technology
At present when the groove of milling pin roll end face, because bearing pin outer surface is comparatively smooth, and be cylindrical, more difficult clamping; Adopt general briquetting assembly to press-fit, need to compress at pin roll end face, groove can not process at one time, and needs again clamping and tool setting, wastes time and energy; And adopt vice to clamp, easily cause bearing pin outer surface to produce indenture, affect surface flatness.
Utility model content
The purpose of this utility model is to provide convenient mounting and clamping, and does not affect the liftable pin roll end face groove milling stationary fixture of surface flatness and processing.
The technical solution of the utility model is as follows:
Liftable pin roll end face groove milling stationary fixture; Comprise base, be separately positioned on the first stopping means on base, the second stopping means and the 3rd stopping means; Described first stopping means comprises the first "T"-shaped lowering or hoisting gear, and " V " shape limited block that inside side, the first lowering or hoisting gear top is arranged; Described second stopping means comprises the second "T"-shaped lowering or hoisting gear, and the clamping device that the second lowering or hoisting gear top is arranged; Described 3rd stopping means comprises the support nail that base transverse part is arranged, and down, support nail nail tip upward for this support nail ailhead.
Described clamping device comprises cylinder, and this cylinder piston rod free end " V " shape limited block is corresponding.
Described first lowering or hoisting gear comprises the first vertical part be connected with base, and the first "T"-shaped portion be connected with " V " shape limited block; Described first vertical part is connected with the first "T"-shaped portion; Described first bottom surface, "T"-shaped portion is provided with the first screw rod, the first vertical part end face be provided with the first screw rod with the use of the first screw.
Described second lowering or hoisting gear comprises the second vertical part be connected with base, and the second "T"-shaped portion be connected with clamping device; Described second vertical part is connected with the second "T"-shaped portion; Described second bottom surface, "T"-shaped portion is provided with the second screw rod, the second vertical part end face be provided with the second screw rod with the use of the second screw.
The beneficial effects of the utility model are: realize axial location to bearing pin 13 by support nail, by " V " shape limited block and cylinder piston rod with the use of, realize the radial location of bearing pin; By the cooperation of first, second, third stopping means, thus realize the clamping of bearing pin, when milling pin roll end face groove, can effectively avoid the rotation of bearing pin and move down; When bearing pin axial length is longer, is realized the lifting of " V " shape limited block and cylinder by the first lowering or hoisting gear and the second lowering or hoisting gear, make bearing pin firm grip, avoid toppling over because of crank.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the utility model will become apparent.
Wherein: Fig. 1 is the utility model structural representation;
In accompanying drawing, 1 is base, and 2 is " V " shape limited block, and 3 is support nail, and 5 is cylinder, and 6 is piston rod, and 7 is the first vertical part, and 8 is the first "T"-shaped portion, and 9 is the first screw rod, and 10 is the second vertical part, and 11 is the second "T"-shaped portion, and 12 is the second screw rod.
Detailed description of the invention
Shown in Figure 1, liftable pin roll end face groove milling stationary fixture; Comprise base 1, be separately positioned on the first stopping means on base, the second stopping means and the 3rd stopping means; Described first stopping means comprises the first "T"-shaped lowering or hoisting gear, and " V " shape limited block 2 that inside side, the first lowering or hoisting gear top is arranged; Described first lowering or hoisting gear comprises the first vertical part 7 be connected with base, and the first "T"-shaped portion 8 be connected with " V " shape limited block; Described first vertical part is connected with the first "T"-shaped portion; Described first bottom surface, "T"-shaped portion be provided with the first screw rod 9, first vertical part end face be provided with the first screw rod with the use of the first screw; Described second stopping means comprises the second "T"-shaped lowering or hoisting gear, and the clamping device that the second lowering or hoisting gear top is arranged; Described clamping device comprises cylinder 5, and this cylinder piston rod 6 free end " V " shape limited block is corresponding; Described second lowering or hoisting gear comprises the second vertical part 10 be connected with base, and the be connected with clamping device second "T"-shaped portion 11; Described second vertical part is connected with the second "T"-shaped portion; Described second bottom surface, "T"-shaped portion be provided with the second screw rod 12, second vertical part end face be provided with the second screw rod with the use of the second screw; Described 3rd stopping means comprises the support nail 3 that base transverse part is arranged, and down, support nail nail tip upward for this support nail ailhead; Realize axial location to bearing pin by support nail, by " V " shape limited block and cylinder piston rod with the use of, realize the radial location of bearing pin; By the cooperation of first, second, third stopping means, thus realize the clamping of bearing pin, when milling pin roll end face groove, can effectively avoid the rotation of bearing pin and move down; When bearing pin axial length is longer, is realized the lifting of " V " shape limited block and cylinder by the first lowering or hoisting gear and the second lowering or hoisting gear, make bearing pin firm grip, avoid toppling over because of crank; By the first screw and the first screw rod with the use of, realize the lifting of the first lowering or hoisting gear; By the second screw and the second screw rod with the use of, realize the lifting of the second lowering or hoisting gear.
Embodiment 2
Described screw nail tip is provided with horizontal platform 14.Because screw is top too sharp, when clamping bearing pin, not only easily wear and tear, and easily cause bearing pin surface to produce pit, affect attractive in appearance; By arranging horizontal platform, when screw nail tip being contacted with bearing pin, adopting the contact in face and face, can effectively avoid nail tip to wear and tear.
